Oh, shit, I'm so sorry, I completely forgot to respond to this on time.

But that is an interesting question! I don't know if I have much of a noteworthy process, really, because it's... Really simple.

Draw circle for a head

Draw hair/face

Draw clothes at complete random, just improvise them

Draw a symbol

Draw horns

That's it thank you

Of course, I have design principles for characters (something I may be planning on expanding on, at some point...)! I'll quickly skim over some.

When I draw hair, I focus more on creating an interesting silhouette with basic shapes and a cartoony feel. Realistic hair doesn't translate well to the Homestuck style, and it's not fun to draw over and over and over and over again.

Outfits are also meant to be simple! Especially in the arm region, because Homestuck sprites tend to be missing arms a lot. Trolls especially don't tend to dress too flamboyantly, and honestly, clothes shouldn't have that dramatic an effect in the end. Most of the beta trolls just wear a shirt and pants, that's really it? So I don't tend to stray too far from there.

Horns are meant to be simple. An addition, not the main focus. Have them be an accent and not something that takes up the whole show.

That's the gist of it! I just don't put a lot of thought into it and keep it simple, that's the end story, here.
